beorn7 af21d456db Unify fingerprinting aka signature calculation.
This fixes https://github.com/prometheus/client_golang/issues/74 .

IT CHANGES THE FINGERPRINTING AND THEREFORE INVALIDATES EACH AND EVERY
PERSISTED FINGERPRINT (I.E. YOU HAVE TO WIPE THE STORAGE TO USE THIS).

This commit removes the LabelValuesToSignature function as it is used
nowhere (and broken in the way it is implemented right now).

Also, remove one more golint warning.

Julius Volz 87a585def8 Adjust various things required for the new storage backend.
- Change Fingerprints to be simple uint64s.
- Deal sensibly with missing metric names.
- Enable finer-grained time resolution.

Merge this concurrently with the merge of the new storage backend into
prometheus/prometheus.

Bjoern Rabenstein 5d40912fd2 Complete rewrite of the exposition library.
This rewrite had may backs and forths. In my git repository, it
consists of 35 commits which I cannot group or merge into reasonable
review buckets. Gerrit breaks fundamental git semantics, so I have to
squash the 35 commits into one for the review.

I'll push this not with refs/for/master, but with refs/for/next so
that we can transition after submission in a controlled fashion.

For the review, I recommend to start with looking at godoc and in
particular the many examples. After that, continue with a line-by-line
detailed review. (The big picture is hopefully as expected after
wrapping up the discussion earlier.)

Matt T. Proud 10dae5d108 Include relevant server model artifacts.
This commit introduces all relevant server-side artifacts such that the
Result streams can be used by external parties for one-off tools and
such.  This will ultimately better enable us to support additional
wireformats with much more ease.
